This was a request and offers something quite different.... it is a tape syle diode compressor. Notice that it runs on 16v biploar power so if you want to power it with normal 9v, a bipolar volatge doubler daughterboard can be used.
*Edit* 270421. Now verified and I got some reports it works perfectly fine using a simple FET Booster up front.
Schematic and info is avaiable HERE.
